Chapter 21, Problem 53PE

1. A 1,00-?O voltmeter is placed in parallel with a 75.0kΩresistor in a circuit, (a) Draw a circuit diagram of
the connection, (b) What is the resistance of the combination? If the voltage across the combination is kept the same as it was across the 75.0-kΩresistor alone, what is the percent increase in current? (d) If the current through the combination is kept the same as it was through the 75.0-kΩresistor alone, what is the percentage decrease in voltage? (e) Are the changes found in parts (c) and (d) significant? Discuss.
